Clubs are responsible for registering all their Administrators, Coaches, Players and Teams with the District Association.

A Player is registered only after her or his Indoor/Outdoor registration has been validated by the District Association and may not play until such time. A Club and/or Team Official allowing an unregistered player to participate in matches or tournaments may be subject to discipline.

A Player must be registered in the correct age category, and proof of age must be submitted at the time of registration.

The Ontario Soccer Association's website lists the categories of players based on year of birth. This information is found on its Operational Procedures webpage.
